PATENT- rrrcn A JOHN HEAZLETT, OF GLASSTON, NORTH DAKOTA.

SPECIFICATION forming part of Letters Patent No. 783,270, dated February21, 1905. Application filed August 17,1904. semi No. 221,049.

To all whmn it nuty concern:

Be it known that I, JOHN H EAZLETT, a citizen of the United States, anda resident of (Jrlasston, in the county of Pembina and State of NorthDakota, have invented a new and Improved Gleaning Attachment forThreshing- Machines, of which the following is a full, clear, and exactdescription.

The purpose of the invention is to provide an attachment to portablethreshing-machines, which attachment gleans or gathers the grain lyingon the ground loose or in bundles while the machine travels forwardthrough the field,

the machine to which the attachment is applied threshing the grain inthe ordinary way, thus rendering it unnecessary to gather the grain bymeans of teams and wagons and convey the grain to the threshing-machinestationary at a fixed point. r

The above-mentioned object is accomplished by attaching to the front ofthe propelled threshing-machine a gatherer and gleaner which as themachine moves onward through the field of grain picks up or gleans thebundles and loose grain, elevating the same to the thresher, where thekernels are threshed out, the threshed grain or kernels being depositedin any receptacle provided for the same, While the straw is disposed ofin the customary manner.

The invention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indieatecorresponding parts in both figures.

Figure 1 is a side elevation of a threshingmachine and the attachmentapplied, parts being in section; and Fig. 2 is a sectional plan view ofthe forward portion of the machine, drawn upon a larger scale.

A represents the frame or casing of the threshing-machine, and B atraction-engine, which is connected with the said frame or casing. Thisengine is a compound engine, being provided with two cylinders 10 and11. The forward portion of the casing of the threshing-machine issupported on suitable wheels 12, and the wheels 13 for thetractionengine serve as the rear supports for the easing. The machine isprovided with the usual elevator and spout utilized to discharge thegrain into a wagon or other receptacle.

C represents a spout which extends from the casing and into which thestraw is blown, and the said spout is carried above the said casing tothe rear, so that sundry of the straw will be deposited on a platform atthe rear of the machine in front of the boiler, enabling a portion ofthe straw to be used for firing.

C represents any form of steering-gear for the machine, and D representsa feed-apron, which is inclined from the front of the machine upward andrearward to the cylinder C in connection with which the ordinary concaveG is employed, and C represents one of a series of band-cutters mountedon a suitable shaft 20, the band-cutter being over the upper portion ofthe feed-apron D. The cylinder is driven by a suitable belt 14, leadingfrom a drivingpulley on the engine to a pulley on the shaft 15 of thecylinder, as is shown in Fig. 2, and a belt 19 is carried from a pulley17 on the cylinder-shaft at the right-hand side of the machine to theband-cutter shaft 20, for example. A second belt 21 is carried from asecond pulley 18 on the shaft of the cylinder to the shaft (Z, uponwhich the upper drum of the feed-apron D is mounted.

E represents the gleaning or gathering attachment which is used inconnection with the feed-apron D and at its rear or inner end is locatedabove the lower portion of the said apron, as is illustrated in Fig. 2.This gleaning or gathering attachment consists of sideboards 22 and abed-board 23, connecting the side-boards, and a shaft 24 is journaled inthe forward portion of the casing or frame A of the threshing-machine,and on this shaft 241 a drum 25 is secured. At the lower ends of theside-boards 22, in advance of the lower end of the bed-board'23, a shaft26 extends from the attachment, and on this shaft 26, between theside-boards 22, the lower drum 27 of the attachment is loosely mounted,and the said drum 2? is provided with series of radial teeth 28, whichas the drum 27 revolves pass through recesses 29, made in the lower endof the bed-board 23. These teeth 28 pick up the bundles and the loosegrain, or, in other words, glean the grain and pass the grain to aconveyer to be hereinafter described. The forward lower end of theattachment is supported by wheels 30, which are mounted to revolveloosely on the outer ends of the shaft 26, above referred to.

The elevator or conveyer for the loose grain and bundles consists ofendless chains 31, which pass over sprocket-teeth on the end portions ofthe drums 25 and 27, and a series of slats 32, which connect the chains31.

' Platforms 33 are supported at the outer faces of the side-boards 22 ofthe attachment, at the lower end of said attachment, each being adaptedto carry an attendant to assist in the orderly taking up of the shocks.Curved guards 34 are secured to the forward ends of the side-boards 22and to the forward ends of the platforms 33. These guards are given adownward and outward inclination and separate the grain or bundles lyingon the ground and which are not to be taken up from the grain or bundleswhich are to be picked up or gleaned and likewise direct the bundles andloose grain to the teeth 28.

The drum 25 is operated so as to give motion to the conveyer or elevatorby means of a belt 35, which passes over a pulley on the lefthand end ofthe shaft 15 of the cylinder and over a pulley mounted on a stud-shaft35, mounted to turn at the left-hand side of the machine, whichstud-shaft likewise carries a second pulley, and a belt 36 is carriedover this latter pulley and over a pulley at the lefthand end of theshaft 24 of the said upper drum 25 of the attachment; but it will beunderstood that the said shaft 35 may be fixed and the two pulleys onthe said shaft be secured together and mounted to turn loosely thereon.

In the operation of the machine as it is driven forward the teeth pickup the bundles and the loose grain, the lower drum 27 carrying the teethbeing driven by the slats 32 at the bottom of the conveyer or elevatorengaging with the rearwardly-extending teeth of the said drum, and thegrain is then carried up by the slats 32 over the upper face of thefeed-board 23 and delivered upon the feed-apron D, where the bands ofthe bundles are cut by the band-cutter, and the grain is then fed by thefeed-apron to the concave and cylinder, where it is threshed in theusual manner.

The gathering or gleaning device E is raised and lowered, as occasionmay demand, by a winch F, connected with said device by suitable cablesf.

Having thus described myinvention, I claim v as new and desire to secureby Letters Patent-- 1. In a threshing-machine, the combination with thefeed-apron thereof, of a gleaning attachment, comprising upwardly andrearwardly inclined elevator-chains, connected at intervals bytransverse slats, and a correspondingly-inclined bed-board provided withside-boards, said bed-board having recesses in its lower end, an upperroller, means for rotating the same to impart motion to the chains, anda lower drum having teeth working through said recesses close to theground, said teeth being engaged by the slats to impart motion to thedrum.

2. The combination in a threshing-machine, of a gleaning attachmentcomprising sideboards, platforms extending laterally therefrom, andcurved guards secured to the forward ends of the said boards andplatforms, sald guards each having a downward and outward inclination asshown and for the purpose set forth.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
